Durability of mortars modified with metakaolin [PDF]

Cement and Concrete Research, 2003
Abstract Results of an investigation to determine the effects of metakaolin additions on transport properties of mortars are reported. Comparisons are made to ordinary Portland cement (OPC) to determine the influence of addition and replacement percentage. Cement is replaced on a mass basis of 5–20% for metakaolin.

Metakaolin in the formulation of UHPC

Construction and Building Materials, 2009
Silica fumes have characteristics that make them exceptional in cement matrices and, in particular, in UHPC. Nevertheless, they have important disadvantages: lack of availability, cost and color. The search for substitute products thus appears important if the use of UHPC is to become more widespread in the concrete industry, e.g.

Pozzolanic activation of metakaolin

Advances in Cement Research, 1992
Metakaolin may be calcined without grinding and suitably activated by Ca(OH)2, Na2SO4, CaSO4 (beta anhydrite) and/or NaOH. The best strengths, 50 MPa from mortar cubes at 18 months, were obtained using Ca(OH)2 and CaSO4 activators. The handling and set properties are similar to those of Portland cement; aluminous C-S-H gel is the best binder.
